The indene moiety is an important unit because of its presence in many chemical catalysts, functional materials and biologically relevant molecules. Herein, we report a facile reaction of arylallenes with benzylic or allylic alcohols through TfOH/Fe(OTf)3 cocatalyzed cleavage of sp3 carbon‐oxygen. In the presence of 5 mol% TfOH and 5 mol% Fe(OTf)3, a range of arylallenes undergo carbocation initiated
茚部分是重要的单元,因为它存在于许多化学催化剂,功能材料和生物学相关的分子中。在本文中,我们报道了通过TfOH / Fe(OTf)3共同催化的sp 3碳氧裂解,芳基烯与苄醇或烯丙基醇的反应很容易。在5mol%的TfOH和5mol%的Fe(OTf)3的存在下,一定范围的芳基亚芳基与烷基醇进行碳正离子引发的环化反应,从而以优异的产率获得结构多样的多取代的茚基。H 2 O是使这种转变具有高度原子经济性和环境友好性的唯一副产物。
